From Latin sine (without) die (day), this is used to refer to an indefinite postponement; to adjourn something without a specified day for future action or meeting. Often used in a legal or governmental context: "The trial was adjourned sine die." "Parliament was dismissed sine die."

It's pronounced either SIGN-eh DIE-eh, or SEEN-eh DEE-eh.

Think what kind of a crap shoot you could have with that.

What about those poor sucker RPG players who think that percentile dice have enough sides for any situation.
